To all whom it may concern;

'Atlanta, in the county of Fulton and State of -Georgia, have invented certain new andusoful improvements in Skylights, of winch the following is a full, clear, and exact descriplights is made of metal.

skylight embodying the invention.

tion, such as will enable those skilled inthe art to which it appertains to make and use the same, reference being had to the accoman iru drawin s forniin )art of this s )801- fication.

This invention relates to improvements in skylights in which the frame supporting the As generally constructed the members of such frames are joined either by soldering or by riveting.

Such structures are not well adapted for fireprooiing purposes, for when subjected to intense heat either the solder melts Or the riveting is broken by the expansion of the parts, which causes a collapse.

In the present invention it is proposed to avoid the use of solder or rivets by joining the parts-composing the frame by interlocking the .diilerent members. By doing this the frame will retain its integrity so long as the metal does not fuse.

The invention consists in the novel construction, combination and. arrangement of parts, such as will be hereinafter fully described, pointed out 111 the appended chums and illustrated in the accompanying drawings. in characters designate corresponding parts, Figure 1 is a perspective view of a section oi Fig. 2 1s a crosssectional view of the same. Fig. 3 is a sectional view on the line 3--3 of Fig. 2. Fig. dis a detail perspective view of part of the ridge. Figs. 5 and (l are detail perspective views of parts of one of the inullions. Fig. 7 is a detail-perspective of part of the sill and bottom rail.

The sill A is shaped to form, cap for the curb B on which the skylight is mounted. It comprises the crown 1 resting on the upper edge of the curb and the sides 2 and 3 respectively contacting with the outer and inner laces of the curb. The outer flange 2 is extended a 'consideraldc distance below the top of the curbfand its lower edge is bent outwardly to form the guard 4, which serves to throw outwardly the drip descending. from the (.lrawings, in which similar reference 7 the skylight. At theeno ()ftlflfl skylight the Be it known that 1, JOHN J. MAIER, a citizen of the United States, and resident of sheet metal forming the crown 1 of the sill 1 bent upwardly to form the gable 0. At the ends of the meeting parts are out to form which are interlocked to form the r'netal. At the lower edge of the side 3 of the sill the metal is folded back on itself and extends upwardly to form the brace 7 for the lower end of the sash. At the upper edge of the brace the metal is bent'back to, form the shelf 8 that rests at its lower edge on the sill 1. There the metal is bent upwardly at right angles to form the base 9 of the bottom rail. The shelf 8 and the base 9 form a trough in the rail extending beneath the lower end of i the sash. This trough serves to catch any moisture that may drain from the under surface of the sash. in. the base 9 are the vent holes 10 to permit the liquid to escape from the trough to the exterior oi" the skylight. The upper edge of the base 9 is folded back on itself a short distance, as at 1.1, and then bent outwardly, as at 12, to form a seat or socket for the lower edge of the light 1). At the edge of the part 12 is the locking tongue 13 to engage the lower ends of the mullions to be described farther on.

T he ridge 1) of the skylight is hollow, hav

section. Its two upper sides 1.4 and 15 of equal length meet at their upper'edges in an :obtuse angle and form the crown oi the t ridge. The two lower sides 16 and 17, also sides, meet at their lower edges in an acute angle and form the abutnients for the upper ends of the mullions that support the sides of the lights. At the upper and lower edges of each abutment are the ledges 18 and 19 i corners of the skylight, as at 6 (Fig. 1), the I are formed from the same piece of sheet ing a four-sided polygonal shape in cross-.

of equal length but longer than the-upper forming the socket to receive the upper ends wardly projecting tongue 22 to engage the .20 (Fi 1). T he mullions F extend from the bottom v r'ail C of. the sash to the ridge E. As they The ridge E is formed pf three pieces of sheet metal, a, b and c respective the side 17, the latter including the flanges 1 20,21, on that side and the tongues 22 and i '26. When the three members are assembled will sufiice for all.

with their tongues engaging with their respective sockets andt said members are firmly locked together so as to form a stiff, substantial ridge.,. The latter is secured to the gable 5 by the tongues 27. at the end of rid e passing through the gable and upset on t eputsideof the same.

are alike in construction, adescription of one At its lowerend the mullion rests on the shelf 8 and abuts the base 9 'ofthe bottom rail; at its upper end it abuts the side 16 of the ridge between the ledges 18- and 19 and rests upon the latter. The 'main 'partof the mullion is formed of asingle piece of sheet metal. At itsu per ed e is the rib 28 formed by a fold in the meta This rib fits at.its upper end between the flange 21 and the ledge 18 and is slotted, as at 29, to receive the flan e 20. At its-lower end the rib enters thes ot 30 of the seat 12 for the li ht in the bottom rail. At the lower edge 0% the rib the metal is bent outwardly at orm ' right angles in-opposite directions to the light seats 31.. When the Inullion is in place these seats 31 are flush with the seat 1 1 andtheflange 21 and form a support for the light D. Atthe. outer edge of each seat 31 the metal is inclined inwardly, as at 32, and

' then outwardly to form the gutter 33, which rojects beneath the side edge of the light. he gutter empties into the trough in the v bottom railC formed by the shelf 8 and the base 9. It serves to collect any drip that may fall from the edge of the li ht and to conduct it to the trough. At t l ends the seats 31 roject beneath the flange 21 and are slotted as at 34, to receive the tongue 21. The flange 21 is also slotted, as I at 35, to receive the rib 28. At their lower ends the seats extend beneath the seat 12 in the bottom rail C and are provided with the slots 36 to receive the tongue13. When the mullion is in place and the several engaging arts register with each otherit is firmly held in lace.

' 011 t e main artof the mullionis the clamping bead (ii that serves to hold the lights in place. It is formed of aastrippf metal having a socket 37 shaped to fit rib 28. Extending oujtwardly e mullions in place,-

ieir upper.

projecting from the upper from the socket part are the flanges 38 havin their edges 39 turned downwardly. When the clamping head is in place its up )er end projects beneath the led e 18 of the r1 ge Eand its lower and extends below the fold 1.1 in the bottom rail C. The flanges 38 project over the adjacent edges of the lights and the downwardly turned parts '39 ress on the glass and the lights are there y held in p ace.

Having thus described my invention, what I claim. and desire to secure by Letters Patcut is v I a 1.- In a sheet metal sash for skylights, a rail comprising a shelf, a base projecting from an edge of saidshelf, a seat for the light )rojecting from said base, a tongue on :the e ge of said seat, said seat and tongue having a transverse slot; and a mullion resting on said shelf, abutting said base and com-. prising a rib at its upper edge engaging the transverse slot in the seat and tongue, and a light-seat projecting from the side of the mullion having a slot to receive said tongue.

2. In a skyhght,a curb and a sash of sheet metal comprising a sill fitting over said curb, a 'bottom rail formed of a shelf resting at the lower edge on said sill, a brace extending from said sill to the upper edge of said shelf, a base projecting from the lower edge of said 9 shelf, a mullion resting on said shelf and abutting said base, and an interlocking joint corinectmg said mullion with said bottom ra1 A 3.
